BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an artificial soil and a method forgrowing vegetation on a sloped surface using the same.

2. Description of the Background Art

On the surface of a slope of cut earth or rock where the environment forgrowing vegetation is poor, applying soil of a suitable thickness ontothe slope will improve the ability of vegetation to be grown thereon.

Installation of a wire mesh with a soil layer over the cut rock surfacehas also been tried. However, the moisture retaining capacity of thesoil is very limited and therefore the soil layer generally must begreater than 12 cm to retain moisture therein. Accordingly, a largeamount of soil is required. Heavy equipment for high pressure sprayingis also required. After application of the layer of soil, the soil has atendency to erode as a result of insufficient adhesion between thesurface of the cut rock and the soil.

As a demand for natural environment is increased nowadays, a desirableartificial soil and a method for growing vegetation are required.

In the conventional method for growing vegetation, a PVC coated wire isfixed to a sloped surface of cut earth, and grass seeds are mixed with avegetation base material. Here, the vegetation base material is mainlycomposed of sewage sludge. Due to inconvenience of the resident in anarea under the construction, a new vegetation base material is requiredto be developed.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the preferred embodiments of thepresent disclosure, examples of which are illustrated in theaccompanying drawings.

An artificial soil and a method for growing vegetation on a slopedsurface using the same according to the present invention will beexplained in more detail.

The artificial soil according to the present invention is produced bymixing peat or grass peat in a concentration of 15˜40% by volume, paperchip or pulp chip in a concentration of 20˜43% by volume, saw dust orbark or wood chip in a concentration of 5˜30% by volume, fermentedanimal waste or dried animal waste in a concentration of 7˜30% byvolume, and a microbe activator, frisol F in a concentration of 2˜10% byvolume; and by adding clay or Silt (SILT) or granular soil in aconcentration of 20˜45% by volume to the mixture.

The peat is estimated to have been accumulated to undergo humificationby an anaerobic analysis in a process that grouped plants in a wet areaare accustomed to live in a dry land while growing and witheringrepeatedly. Accordingly, peat eroded as organic matters are decomposedexists in a hot and dry area, whereas peat in a slow decompositionprocess or in no process exists in a cold area with moist winter.

The peat has a high nutrient retaining capability and moisture retainingcapability, and is not secondarily fermented, thereby not causing adamage to plants but being beneficial to the plants.

A pH of a soil suitable for a plant growth is in a range of 6˜7.5, and apH of a high level is 6˜6.5. A pH of the peat is 6.8, which is suitablefor a plant growth.

The peat has an organic matter (OM) in a concentration of 42% by volumehigher than that of the sewage sludge cake in a concentration of 25% byvolume, which is beneficial to a plant growth. Generally, a soil havingP₂O₅ of 200 ppm or more is classified into a high level, and a soilhaving able P₂O₅ of 200 ppm˜100 ppm is classified into a middle level.The peat has P₂O₅ of 184 ppm, which is suitable for a plant growth.Also, the peat has a good moisture retaining capability of 65/97(%/time).

<Table showing an analysis for components of paper chip and pulp chip>Moisture retaining capability OM T-N P₂O₅ (%/time) (%) (%) (ppm) pH85/97 56 2.63 180 6.5

Once paper chip is made to be powder by being soaked to water, the paperchip has the same moisture retaining capability as pulp chip. The paperchip and the pulp chip have a high moisture retaining capability, andcontains a good available phosphate.

Grass peat is generated in a similar way to the peat, and is sometimesclassified into the same material as the peat. However, the grass peatis different from the peat as follows. The grass peat is clayey peatgenerated as plants including peat trees are accumulated, which issimilar to black clay. On the contrary, the peat is generated as herb,moss, etc. are accumulated, which is a fine fiber and has a small massof about 0.5% by volume. The grass peat can be used as an organicfertilizer on a grass field, or can be used for plants including crops.

<Table showing an analysis for components of peat> K₂O(%) T-N(%) OM(%)P₂O₅(ppm) pH 0.19 1.78 85 726 5.5

The grass peat has a moisture cell that occupies 89% by volume, and hasa good air permeability, moisture retaining capability, and nutrientretaining capability.

As a microbe activator which is a nutrient for growing a plant, frisol Fis used.

Once the frisol F is mixed with soil, the frisol F remains at the soilfor a long time without being lost. Accordingly, the frisol F has aneffect that forest soil is covered with fallen leaves. The frisol F is agranular material produced by mixing a microbe that is perished byprocessing a microbe mass at a temperature of 130° C. with nutrient.Accordingly, the frisol F circulates in correspondence with nutrientinside the soil, and supplies the nutrient that can be easily used at aroot to a plant by accelerating a complicated microbial operation. Thefrisol F enables the soil to be serve as good soil and to have a strongendurance against germ or difficulties.

Even if both the saw dust and the bark or wood chip have a weak acidity,there is no problem in an entire pH of the artificial soil since othermaterials have a pH close to a weak alkalinity. Since the saw dust andthe bark or wood chip have good available phosphate and have a greatamount of organic matter, they activate aerobic microorganism to befermented when being mixed with animal waste, etc., and perform amoisture retaining capability and a nutrient controlling function whenbeing mixed with the artificial soil.

Once a saw dust is mixed with an animal waste and then is decayed, themixture has an enhanced nitrogen and phosphoric acid. The mixture has ahigh nutrition, a sufficient organic matter, a good microbe-activatingfunction, and a high latent effect, thereby enhancing a quality of theartificial soil when being mixed with the artificial soil.

An artificial soil is mixed with clay or granular soil or Silt (SILT) inorder to control a solid phase, a liquid phase and a gas liquid thereof.A small particle has a good moisture retaining capability but has a poorair permeability. On the contrary, a large particle has a low moistureretaining capability but has a good air permeability. A proper amount ofthe small and large particles are mixed with the materials of theartificial soil to compensate for each characteristic, thereby producinga good artificial soil.
